Effective and safe use of pain and anti-inflammatory medications in teaching dental clinics requires a comprehensive knowledge base of the various drug agents. The purpose of this study is to assess the knowledge and perception of student dentists in various dental schools in Saudi Arabia in the use of pain and anti-inflammatory drug therapies. This study could help identify common areas for collaboration and improvement in healthcare delivery between pharmacy and dental medicine in Saudi Arabia.</p></div><div><h3>Methods</h3><p>328 student dentists enrolled in traditional six-year dental program in Saudi Arabia were invited to participate in a voluntary online survey. The brief survey consisted of 21 multiple choice questions and was delivered as a secure link through email and private social media messaging services. The survey permitted only 1 attempt per user.
